io_queue_wait - Wait for io requests to complete
#include <errno.h> #include <libaio.h> int io_queue_wait(io_context_t ctx, const struct timespec *timeout);
io_queue_wait() attempts to read an event from the completion queue for the aio_context specified by ctx.
May return 0 if no events are available and the timeout specified by when has elapsed, where when == NULL specifies an infinite timeout. Note that the timeout pointed to by when is relative and will be updated if not NULL and the operation blocks. Will fail with -ENOSYS if not implemented.
On success, io_queue_wait() returns 0. Otherwise, -error is return, where error is one of the Exxx values defined in the Errors section.
